These pretty plants are grown for conservatory decoration, T. Fournierii being one of the prettiest species, but not a florist's flower. T. Asiatica is often used with us as a bedding plant, being a fine plant for an edging. Its blue and violet flowers are very pretty and give a change from the prevalent reds of our flower gardens.
It can be raised from seed sown in February and afterwards grown on in flats or put into small pots and planted out when settled warm weather arrives.
It can also be carried over winter by putting in cuttings in August and further propagated during winter and spring. Any good ordinary soil will grow it. Fumigate, for it is troubled with greenfly, and it requires a high temperature at all times. In the flower garden it should have a rich soil, and it thrives well in partial shade.
